thanks guys, will try both ways. the manual says when bridged to use channel 1 (and turn the gain on channel 2 off). So assuming its channel 2 (the right) is the inverted one where i need to switch the black to red and red to black. I guess since the bridge switch is on, that I'll continue to keep the channel 2 gain(volumn) all the way off, correct? will reply back if i can tell any difference between the two options.
